CULTlVATO R.

SPECIFICATION forming part of Letters Patent No. 243,507, dated June 28, 1881. Application filed February 15, 1881. (No model.)

To all whom it may concern Be it known that I, HARVEY W. CHAMBER- LAIN, of Lockport, in the county of Will and State of Illinois, have invented a new and use ful Improvement in Cultivators, of which the following is a specification.

My invention relates to devices for connecting the tongue or pole of a modern cultivator with the beam thereof.

The object of my invention is to provide mechanism for cultivators by means of which the beams thereof may be elevated or depressed, or the space between them may be increased or diminished-to conform to the various wants of agriculture.

The invention consists in the combina ion of parts hereinafter described.

In the accompanying drawings, in which similar letters of reference indicate like parts, Figure 1 represents a side elevation of a cultivator with my invention thereto attached. Fig. 2 is a superficial view of a portion of the coupling by which the beam is attached to the adjustable post. Fig. 3 is an inverted view of the standard, showing the method by which it is attached to the tongue or pole. Fig.4.is an inside view of one-half of the coupling referred to in Fig. 2. Fig. 5 is a perspective view of the adjustable post connecting the standard with the coupling referred to in Figs. 2 and 4.

Referring particularly to the drawings, A is the tongue or pole; B, the slotted lugs, O, the standard, attached by the slotted lugs B to the tongue or pole A by the bolts 2 2, said bolts extending through the slots 00 w, and arranged in such a manner that when loosened the standard 0 may be adjusted by moving it forward or backward through the slots ac x in the slotted lugs B, at right angles to the tongue or pole A.

O is the journal-bearing in the standard 0.

S is the adjustable post, connected with the standard 0 through the journal-bearing O in said standard, and held in place by the setscrew 0. Said set-screw 0, when loosened, permits said adjustable post S to be raised or lowered at pleasure.

R is the coupling by which the adjustable post S is attached, by means of the couplingbolt i, to the beam H. Said coupling may be detached from the adjustable post S by loosening the coupling-bolt e.

D is the annular flange-groove in the coupling R, and D the annular flange-ring on the post S, so constructed as to fit closely in said groove D and permit the adjustable post S to revolve therein or the beam H to be moved laterally in either direction. In this connection it may be noted that the coupling R is so attached to the beam H by means of the coupling-boltz' as to permitsaid beam H to be raised or lowered at will.

Having thus described my invention, what I claim is- The combination, withthe beam H and pole A, of a coupling, R, having the groove D, a post, S, provided with the flange D, and the standard 0, provided with the slotted lugs B B, bearing 0, for receiving the end of the post S, and thumb-screw 0, for adjusting said post, substantially as described.
